380/381 mm Rubber Tracks for Compact Track Loaders

Select 380/381 mm rubber tracks by size group and version

For 380/381 mm rubber tracks, the specific size group determines the technical assignment. In the LIS® range, the variant 381/42/100.5SRT is currently particularly relevant. This specification stands for 381 mm width, 42 links, 100.5 mm pitch and SRT version.

The category is often searched in the 380 mm market environment, while the current technical article dimension at LIS® is listed with a width of 381 mm. For purchasing, workshop and parts trade, the track marking, technical size data, guide geometry and machine assignment should therefore be checked together.

Match LIS® article data with market-standard size notations

For rubber tracks, size data may be arranged differently or shown in rounded form depending on the data source. LIS® articles such as 381/42/100.5SRT are displayed in the shop in the order width, number of links and pitch. In the market, the same technical size combination is often searched as 381x100.5x42SRT or 381x100,5x42SRT, meaning width, pitch and number of links.

In the 380 mm market environment, specifications such as 380x102x42, 381x101.6x42 or similar notations may also appear. These specifications must not be treated as automatically identical. The decisive factors are the match between width, pitch, number of links, version, track marking and machine assignment.

Check 381/42/100.5SRT and the current machine assignment

The size group 381/42/100.5SRT is currently particularly associated with compact track loaders from the Caterpillar/CAT 247 and 257 environment. Depending on the article assignment, models such as CAT 247, 247B, 257 or 257B may be relevant.

These machine designations do not replace the technical check. Before ordering, 381 mm width, 100.5 mm pitch, 42 links, SRT version and the existing undercarriage variant should be matched with the track marking and the article data in the LIS® shop.

Check track marking, machine model and undercarriage together

If the existing rubber track is still readable, width, pitch, number of links and version should be checked using the marking. If the marking is no longer clearly visible, machine model, series, year of manufacture and undercarriage variant should also be used for identification.

Manufacturer or model names alone are not sufficient for clear ordering if different undercarriage variants or different track versions are possible. A 380/381 mm rubber track must match the existing guide geometry and the machine assignment shown in the article.

Check adjacent undercarriage components if identification is unclear

If identification is unclear, adjacent undercarriage components should also be checked, especially drive sprockets, idlers, track rollers and track adjusters. A 380/381 mm rubber track must match the existing undercarriage geometry, not only the machine designation.

380 mm rubber tracks, compact loader tracks and rubber crawler tracks

Depending on market terminology, 380/381 mm rubber tracks may also be referred to as 380 mm rubber tracks, compact loader tracks, compact track loader tracks or rubber crawler tracks. This category covers rubber tracks for machines with rubber-track undercarriages, not steel tracks.

If a steel-track undercarriage is required instead of a rubber track, the relevant undercarriage categories are track chains, complete track chains, track shoes or rubber pads and rubber plates, depending on the required component.

Further rubber track widths

LIS® 380/381 mm rubber tracks are used in OEM quality. If the existing track has a different width, the main category rubber tracks leads to further widths from 150 to 900 mm. Common technical entry points also include 350 mm rubber tracks, 370 mm rubber tracks, 400 mm rubber tracks and 450 mm rubber tracks.
